The Nike Air Max BW originally dropped back in 1991 and was apart of the Nike International Series. You may also know this historic sneaker by its other name, The Air Max Classic. The shoe's "BW" suffix refers to the striking "Big Window" bubble in the heel if you didn't already know. The BW has a distinct style with a combination of materials on the upper, anatomically engineered PU midsole, maximum volume Air-Sole unit in the heel, and a BRS 1000 carbon rubber waffle outsole. Nike is bringing back the OG colorway that this sneaker is best known for.
